ITP Star Styli with ruby ball tips are precision measuring probes designed for demanding metrology tasks. This 90° star stylus (model SCM303005040/90°) features an M3 XXT mounting thread and a 31 mm measuring length, crafted to reach deep features, measure large diameters, and handle undercuts with stability.

• Tip configuration: Ruby ball tips on both ends provide repeatable contact and wear resistance for extended gauging sequences.
• Angle: 90° right-angle design enables side-entry measurements and access to bottom holes, recesses, and threads.
• Thread: M3 XXT mounting thread ensures secure, compatible attachment to standard probe fixtures.
• Measuring length: 31 mm measuring length offers reach into deep features while minimizing cantilever deflection.
• Construction: Robust steel body with fixed probe arms for stability and repeatability across long gauging lengths.
• Applications: Ideal for measuring large bore diameters, undercuts, threaded features, and difficult-to-reach areas in precision parts.

Designed for reliability in inspection and manufacturing environments, the ITP Star Styli SCM303005040/90° helps you capture accurate data where standard straight styli fall short. Use it in CMM workflows, fixture-based measurements, or manual gauging setups to streamline a wide range of part verification tasks—from rough checks to tight tolerance assessments.
